High temperature coated sand: The sand generally refers to large-coated sand thermal strength, heat-resistant long time, high temperature deformation coated sand recycling machine manufacturer, rather than its high refractoriness. It is through a special formulation technology process (usually when a certain amount of inert materials such as silica sand coated sand mill, high chromium ore, carbonaceous material or other inert materials, etc.), to produce a superior high temperature performance and integrated casting The new coated sand properties. High temperature, high strength, low inflation, low gas, slow gas evolution and other characteristics. Especially for complex thin-walled precision iron castings (such as automotive engine block, cylinder head, etc.) as well as demanding castings (such as container train horn and brakes buffer housing, etc.) production, can effectively eliminate the sticky sand, regeneration and quality of deformation, thermal cracking and porosity and other casting defects coated sand control with the continuous improvement of the human environmental protection requirements, coated sand recovery and regeneration becomes more and more important and urgent. The most commonly used method of mechanical recycling and renewable thermal regeneration. The basic principles of mechanical reproduction is the use of high-speed rotors wheels (approximately 3500r / min) and the slow rotation of the rotary frame gap between the (5-10mm) of the old sand friction, in order to achieve the removal of resin and sand surface for the purpose of shaping sand, dust generated through the ventilation dust processed in the coated sand production areas should be strengthened following two aspects: (1) made pollution-coated sand coated sand recycling machine manufacturers, mainly from the following several aspects: ① reduce the amount of resin and curing temperature; ② coated sand to improve the overall performance of coated sand recycling machine supply, especially in high temperature performance; ③ strengthen research and pollution-free phenolic resin alternatives;. (2) increasing the regenerative capacity of coated sand coated sand coated sand production equipment package recycling the majority of experts has been a subject of concern coated sand regeneration, now coated sand regeneration equipment is expensive and regeneration efficiency is not high, production efficiency 5 t / h of thermal regeneration equipment prices in 1200-1600 yuan, regeneration coated sand cost 65-90 yuan / ton, so the cost can not be covered for the domestic foundry sand reclamation enterprises machine manufacturers, Qingdao Heng (certified), coated sand regeneration by Qingdao Heng Machinery Co. Qingdao Heng Machinery Co., Ltd. (www.thjidian.com) is in Qingdao, Shandong Cleaning equipment leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
